Evidence Explorer
Verify QCOS certification results independently. Every experiment produces a SHA-256 evidence hash that proves data integrity — you don't need to trust us.

What QCOS Evidence Technology Guarantees
Tamper Detection
Any modification to experimental data — even a single bit — completely changes the SHA-256 hash. Tampering is mathematically impossible to hide.
Independent Verification
Anyone can recompute the SHA-256 hash from raw data and compare against the published hash. No SoftQuantus dependency required.
Chain of Custody
Five cryptographic layers ensure complete provenance — from circuit input to final signed result. Every step is hash-chained.
Published Evidence Bundles
All evidence bundles from the QCOS v3.2.0 Certification Campaign (February 2026). Click each bundle to explore its cryptographic chain.
